IMPROVEMENT IN VEHICLE FIFTH-WHEELS.

Specification forming part of Letters Patent No. 210,675, dated December 19,1878; application filed September 12, 1878.

To all whom. it may concern:

Be it known that I, JOHN DEEBLE,0f Southington, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in King-Bolts for Carriages, of which the following is a specification My invention consists of the clip, adapted to be placed over the axle and under the frictionplatesecured to said axle, and having a hollow trunnion projecting upward a distance equal to the thickness of both friction-plates, in combination with the ordinary .frictionplates and the king-bolt passing through said hollow trunnion, as hereinafter described.

In the accompanying drawing, Figure 1 is a frontelevation of a fifth-wheel with a kingbolt which embodies my invention; and Fig. 2 is a vertical section of the same on line a, m of Fig. 1.

My invention is designed for that class of fifth-wheels in which the longitudinal frictionplates between the axle and head-block bear directly one upon the other.

A designates a portion of the spring B,the head-block; G, the axle, and a b the longitudinal friction-plates, all of which are substantially the same as the ordinary fifth-wheel of this class. 0 designates the king-bolt clip, adapted to be placed under the friction-plate I), over and surrounding the axle, and secured in the ordinary manner. On the upper side of this clip I form a circular projection or trunnion, d, of a length fully equal to the combined thickness of the plates (6 b, and of a diameter considerable larger than that of the ordinary king-bolt. The plates to b are bored out at the middle of their length to receive and fit the trunnion (1, whereby they are journaled on said trunnion. This trunnion is made hollow or bored out on its axial line to receive the plain king-bolt k, the same passing through said trun11ion,-being separately constructed, and driven in so as to fit snugly before the clip is placed upon the axle. The head-block is held in place by a nut on the end of the kingbolt, as in ordinary king-bolts.

By my invention I produce a clip king-bolt for the class of fifth-wheel shown in a cheap and economical manner, and one which has an increased bearing-surface for the journals of the longitudinal friction-plates, which sustain the entire weight of the head-block, so that the clip, although narrow, will not be depressed into the wood of the axle.

I am aware that a king-bolt and clip made in one solid piece has been applied to this class of fifth-wheels, and also to fifth-wheels of a different class, and I hereby disclaim the same.

I am also aware that an elevated saddle-clip for king-bolt is old, the same having a socket in its upper end to receive a trunnion on the head-blocl;, through which the kingbolt was passed; but said clip was not adapted to be placed over the axle and under a plate secured to said axle, but the entire weight of the head-block bore upon the clip. Said clip and kingbolt are hereby disclaimed.

I claim as my invention The king-bolt clip 0, adapted to be placed over the axle and under the friction-plate secured to said axle, and having a hollow trunnion, d, projecting upward a distance equal to the thickness of both friction-plates, in combination with the ordinary friction-plates a b and the king-bolt h, passing through said hollow trunnion, substantially as described, and for the purpose specified.

JOHN DEEBLE.
